Open-AudIT is tool for scanning and compiling an inventory of a network environment. So far I have used it to get a complete picture of all of the hardware and software on the LAN. I have been very impressed with the features that just work out of the box. The one link to Dells service tag check works great.

5) Fire up the web browser to the IP/Site to test and Open-Audit will walk through setting up the MySQL database.

Once everything is configured Go to the Forums to get info on how to run your first audits. I found this thread to be a great starting place.

UPDATE: From the comments below.

Once you unzip the folder in your working webserver, you can access the openaudit site with the ip address in the url. If you open it to the setup page, it will walk your through configuring the Database connection.
